GEORGE ESSER, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO PEMBROKE S. EDDY, OF SAME PLACE.

SEPARABLE STUD.

SPECIFICATION forming part of Letters Application filed January 31, 1890.

To all whom it may concern.-

Be itknown thatI, GEORGE ESSER, of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Separable Studs, of which the following is a specification. 4

The nature of my invention consists in the improved construction and arrangement of the several parts of the stud, as hereinafter To fully set forth.

Figure 1.1epresents a side elevation of the improved separable stud. Fig. 2 represents the shoe in axial section connected to the post of the head of the stud. Fig. 3 represents a side elevation of the head of the stud and the attached wire post. Fig. 4 represents a top View of the pusher-guiding plate of the shoe. Fig. 5 represents an edge view of the same. Fig. 6 represents a top view of the shoe with the covering-p1ate removed, showin g the pushers in position. Fig. 7 represents a plan view of the pushers removed from the shoe.

In the accompanying drawings, A repre- 2 '5 sents the head of the stud, to which is firmly attached the wire post B, the said post being tapered at its end and provided with the annular groove a. The shoe 0 is formed of a cup I, which is provided with opposite elono gated perforations c c to receive the pushers H II, a covering-plate E, provided with a hollow post F, adapted to receive the wire post B of the head A and the pusher-guiding plate G. The plate G is provided with the central 3 5 perforation or depressed recess (1 and the opposite struck-up portions 6 6, thus forming a recess f at the upper side of the plate G, adapted to receive the pushers H H, the struckup portions 6 6 serving to support the cover-- 0 ing-plate E and to allow sufficient space between the covering-plate and the bottom of the recess ffor the proper operation of the pushers. The pushers H are provided with Patent NO. 429,089, dated May 27, 1890.

Serial No. 338,777. (No model.)

a head portion g, a limiting-shoulder h for the forward movement of the pusher, acatch portion 1', and a spring portion j, the spring j of each pusher being arranged to act against the back of the head of the opposite pusher,

as shown in Figs. 7 and S. In putting the parts of the shoe together the pusher-guid- 5o ing-plate G is first inserted into cup I, and the pushers H H placed in position, as shown in Fig. 7, and then the coveringplate E is placed upon the.plate.G, so as to rest upon the struck-up portions 6 e and the edge of the cup I turned over the edge of the plate E, as shown in Fig. 4.

When the pushers H II are pressed inward, the catches i 'i will be moved out of the groove a in the post B, thus releasing the same to allow the removal of the head of the stud from the shoe, and upon releasing the heads g of the pushers from pressure the resilience of the springs j, which bear against the inner side of the heads g, will serve to carry the pushers outward until the shoulder It strikes against the inner side of the rim of the cup I.

I claim as my invention- In a separable stud, the combination, with the head A and post B, provided with the catch-gr0ove a, of the cup I, provided with the opposite perforations c c to receive the pushers, the pusher-guidin g plate G, provided with the raised portions 8 e and the opening d, the pushers II II, provided with the head g, the shoulder h, the catch t', and springj, and arranged with each other so that the spring of one pusher will rest against the opposite pusher, and the covering-plate E, provided with the hollow post I, substantially as described.

GEORGE ESSER.
